MANURE-SPREADER.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed January 27, 1913. Serial No. 744,423.

To all whom it may concern:

Be it known that I. lVILLiAM C. JIRDIN- s'rox, a citizen of the UnitedStates, residing at Moline, in the county of Rock Island and State ofIllinois, have invented new and useful Improvements in Manure-Spicaders,of which the following is a specification.

My invention relates to improvements in mechanism for spreading manure,or similar material; and an object of my improvement is to loosen, asmuch as possible, the manure before it isacted upon-by thendistributingmeans. Other objects of myinvention will be described more fullyhereinafter.

Referring .to the drawings in which similar numerals indicate identicalparts in the various figures:

Figure 1 is an enlarged view of the rear end of a manure spreadershowing my improvement. and the box and rear-wheels in dotted lines.Fig. 2 is a plan view of Fig. 1. Fig. 3 is a section on the line .r-:rof Fig. 2. Fig. 1 is a section on the line ;z y of Fig. 2.

The box-shapedbody 1 is mounted on wheels as usual, the operating powerof the spreading mechanism being derived from the rear-wheels 2.Formingthe bottom of the body 1 is a conveyer 3. and consistingpreferably of slats a secured to a chain passing around one or moresprockets 5 and adapted to deliver the manure rearwardly toward thedistributer.

T he sprockets 5 are mounted on a shaft 6 journaled in suitable bearingson the box 1; a gear 7 engages with a similar gear 8 rigid on a shaft 9which is also journaled in suit able bearings 10 on the bottom of thebox 1. A sprocket 11 is also rigidly mounted on the shaft 9 to whichmot-ion is imparted through a chain 12 passing around a sprocket 13 onone of the rear wheels 2, so that as the machine advances the apron isoperated to move the load rearwardly.

\Vhen the machine is loaded the manure is generally in a compactedcondition, which is increased by the motion of the machine whiletransporting the load from the place of loading to the place of distri-'bution; it is very desirable that this compacted state be destroyed, asfar as possible, and the manure be loosened and broken before itis-scattered by the distributer, and for this purpose I have provided anauxiliary conveyer 14 rearwardly of the main conveyer 3, acting betweenthe latter and the distributer, and which I will now describe.

Pivotally mounted on the shaft 9, and extending rearwardly are brackets15 and 16, having suitably journaled thereon rearwardly a shaft 17, overwhich the auxiliary "conveyer 14 travels, the latter being preferablyconstructed similar to the main conveyer 3, and movable in a similarmanner by means of sprockets on the shafts 9 and 17. Bars 22 and 23rigidly connect the brackets 15 and 16. A distributer 24, comprising adrum having teeth, is secured on a shaft 25 journaled in bearings'QG and27 on supports and which may be integral with the brackets 15 and 16, orsecuredthereon in any suitable manner.

To impart motion to the auxiliary conveyer 1-l and the distributer 2 1,I employ a disk 30 which is rigidly mounted on the shaft 9; a shaft 31is journaled in bearings on the bracket 15 and carries thereon a bevelpinion -On the rear of the shaft 31 is rigidly secured a bevel pinion 33meshing with a similar pinion 34: on the shaft 17, and transmittingmotion to the auxiliary conveyer 14; asprocket 35 is, rigidly mounted onthe shaft 17, with which it revolves,

I and which is connected to a similar sprocket 36 on the shaft by achain 37 revolving the distributer to carry the manure up and over tothe rear;

To prevent loss of manure over the sides of the auxiliary conveyer 14when the latter is in operation, I provide shields'38 and 39 secured tothe auxiliary conveyer frame, and adjustable with it, and projectinginto the rear of the box 1- with whichjthey are in close contact, andheld againstlateral movement by bolts on the box 1 operating in slots 40and 41,

The auxiliary conveyer 14 is mounted and operates in a plane lower thanthe plane of the main conveyer 3, and its rear is adjustable above orbelow a horizontal plane, or its normal position of parallelism with themain conveyer 3, by meansof .chains or cables 42 and 43 secured to thebrackets 15 and 16, and leading over idle pulleys 44 and 45 on the sidesof the box 1 to drums -16 and 47 on a shaft 18 which is mounted insuitable bearings on the box 1; an, ordinary hand crank is used tooperate the shaft 48,

which has a ratchet 49 thereon, and with which a .dog 50 engages toretain the auxiliary conveyer in any position of ad ustment.

The auxiliary conveyer 14 may be oper-- ated at the same speed as themain conveyer or at a greater or lesser speed as may be desired, andwhile I have shown one Way of operating my improvement, I do not limitmyself thereby, as it is obvious that other arrangements of gearing willaccomplish the same purpose.

As the manure is carried rearward by the main'conveyer 3 and reaches theend thereof, it drops abruptly to the auxiliary conveyer ll which tendsto loosen and spread the manure before it reaches the distributer :24,and if the auxiliary conveyer is moved at a greater speed than the mainconveyer the manure will be still further loosened, while a slower speedto the auxiliary conveyer will tend to present the manure to thedistributer in greater volume. Similar effectsare obtained by adjustingthe rear of the auxiliary conveyer, as shown in dotted lines big. 1, ifgiven a downward inclination the effect upon the manure will be toloosen it, an effect that will be materially aided by increasing thespeed of the auxiliary conveyer above the speed of the main conveyer,but such an increase diminishes the volume of manure presented to thedistributer; a decided advantage is obtained, however, in operating theauxiliary conveyer with a downward inclination, as the distribution ofthe manure occurs closer to the ground than can be obtained otherwise,resulting in a more even spread, the quantity of manure distributeddepending upon regulation of the speed of the auxiliary conveyer; whenthe auxiliary conveyer is adjusted to an upward inclina:

tion, however, an increased speed is desirable.

Means upon the rear of the box 1 to hold the manure therein duringloading or transportation, and means for throwing the conveying anddistributing mechanism out of operation are commonly employed, but Ihave not shown or described such, as various types may be used without,in anyway, affecting or altering the scope of my invention, which I donot limit to the details of the construction shown and described.
